Probably an ignorant question, but I am going to ask anyway.

It's been a while since I have messed with my truck since EagleMark helped immensely in the last bit of tuning I have done.

A few days ago, I finally got around to doing the MPG via the fill up the tank, drive a bit, fill up again and do the math. While I know this is not a very accurate method, I'm looking at about 20-23 mpg.

So I decided to whip out the toughbook and do some logging.

Then, I started playing with the "dash" display and changing around things.

But then I noticed something odd,and maybe it's just me, but it seemed that the data I am seeing is off from the setup I was using before.

By setup, I mean the version of xdf/adx file I was using.

I was using a custom dash modified a little from the v5.0 and I don't remember what version of xdf.

Now that I have seemed to have beat around the forest, my question is regarding the data stream that is recorded.

Is the raw data recorded from the ECM that is stored in the log file, or, is the data logged and recorded after being decoded by TunerPro?
